Recently the Ministry of Finance and Economy of Korea launched two new project delivery systems called "Best Value Contract (Design-Bid-Build)" and "Bridging Contract (Design-Build)" in October of 2007 by revising enforcement ordinances of "Act on Contracts to Which the State is a Party". These project delivery systems require the bidders to submit technical proposal adjusted to the project characteristics and objectives for selecting the contractor by evaluating technical proposals. This research aimed to suggest guideline to effectively operate the project delivery systems described above. To reach the goal of the research, the framework of the operation model was developed, which includes the four categories: the standard bidding process, the technical proposal requirements, the technical proposal evaluation criteria, and the award methods. The contents of the four categories above were fulfilled throughout conferring with the advisory experts. In particular, the award methods, which are the important decision-making factor in the perspective of the owner, consist of four types: Low Bid-Fully Qualified, Weighted Criteria, Adjusted Bid, and Adjusted Score. The quantitative features and application criteria of these four types of award methods were suggested throughout the simulation using the virtual case.

Full system of turnkey deliberation committee in 2010 was abolished and permanent Deliberation committee was introduced. So far, ordering organization selected the best method suitable for the design and comprehensive evaluation method in the turnkey bid construction. Comprehensive evaluation method have bid price design score coordination, weighted basis, the best design approach fixed amount, five successful bidder decision method in addition. Design deliberation branch committee in the successful bidder decision way configured and operated branch members of special design consultation committee, But main agent changed from committee deliberation pull system to permanent committee deliberation, as well as and The lobby burden was not improved. This similar to the past at the portion of the design deliberation and the way of the design deliberation in the turnkey bid construction. Therefore it is necessary to improve the design deliberation system. In other words, design score and technology competition should be adapted to determine a successful bid. This study suggested the operating system of the design deliberation, the decision method problems of the successful bidder and ways to improve the design deliberation.

The selection of the reasonable project delivery system (PDS) is crucial for a successful performance of a project, which means to achieve project objectives. Furthermore, the project performance has been tightly related to the selection of PDS appropriate to pertinent project characteristics. In this context, the ministry of finance and economy of Korea launched two new project delivery systems called "Best Value Contract (Design-Bid-Build)" and "Bridging Contract (Design-Build)" in October of 2007 by revising enforcement ordinances of "Act on Contracts to Which the State is a Party". For efficient operation of the new project delivery systems, this paper suggested a PDS selection model which supports decision making of the reasonable PDS for a pertinent project by assessing characteristics of the public construction projects, both quantitatively and qualitatively. In addition, a PDS performance evaluation model was proposed in order to get feedback on the result of the PDS selection and the operation for the succeeding project. The standard models suggested in this paper might be used as a tool to support the decision making of the public organizations.

Turnkey and alternative-design contracts was introduced operation in the country from january 2004 to February 2010. this was introduced operation. The selecting method of contractor for turnkey projects has being operated by an open forum type that consists of technical committee and appraisal committee in an integrated design approach deliberations. But to improve the operation of the problems, the government is operating design review committee consisting of the central, local and special design advisory committee in march 2010. But this system has also been suggested as still problems, too many contracts by large companies, increasing of design cost and excessive competition. This study is intended to contribute that turnkey and alternative-design contracts can be well operated in domestic construction markets. In this paper suggests some improvement methods and operational problems caused from application of an open forum type for selecting contractor of turnkey project.

With the current trend in the industry toward increasingly complex, diversified and large construction projects, advanced countries in the construction field have already introduced and applied a variety of methods for placing orders in order to cope with such changes in construction circumstances. In Korea, there have been efforts to continuously improve approaches to placing an order. With the aim of diversifying the methods of Delivery Systems, the "Technical Proposal Type Bid," and the "Design Competition and Technical Proposal Type Bid" were introduced through a revision of Korea's contract law enforcement ordinance. In line with the government's efforts, criteria for a method of placing an order that is suitable for a public construction project should be presented. This study enumerates the current issues using a survey for construction projects already placed and an analysis of the current status, and presents the selection criteria for Delivery Systems by business type as an improvement for the problem.

Clients demands have been changed by construction circumstances such as high-technology, mega-projects, and the complexity of construction. Advanced foreign countries have already introduced and applied new project delivery systems(i.e, CM, DB, etc.) to deal with the change of such that. Recently, Korea also launched two new project delivery systems, "Best Value Contracts to which the State is a Party" to provoke the project delivery system, which helps a public owner select a project delivery system appropriate to the project characteristics. Even though government has made his efforts as stated above, some clients have still used those to public construction projects uniformly. That is because there are not a selection criteria of project delivery system for clients. Therefore, this paper proposes the selection criteria of project delivery system based on project types in the public large construction projects.

한국건설산업연구원은 8 · 31 대책 이후 주택 시장의 불안정은 주택 수급 불균형 때문이라며 재건축사업을 활성화해야 한다고 진단했다. 도심지 내 주택 공급 문제의 근본적인 해소를 위해서는 각종 규제로 인해 교착 상태에 빠져 있는 재건축 사업을 활용해야 하며 이를 위해 경쟁입찰을 통해 선정된 사업시행자가 '일괄 매수 후 개발 및 분양하는 방식'을 새롭게 도입할 필요가 있다는 주장이 제기됐다.

전통적으로 주요 EPC(설계, 구매, 시공) 공사는 최초의 엔지니어링 작업(FEED : Front End Engineering Design)을 한 후, 경쟁입찰을 하여 총액계약(Lamp Sum)으로 공사를 수행했다. 최근에 EPC시공자의 위험부담을 줄이는 한편, 발주자는 경쟁적인 시공자를 확보할 수 있는 기회를 확대하면서 협상기간을 단축하교 조기착공을 위해, Lump Sum 가격을 늦게 결정하는 방법을 고려한다. CLST(Converted Lump Sum Turnkey)계약방식은 최초의 엔지니어링 작업을 한 후 경쟁입찰을 통해 1차 계약을 맺고(설계 및 특별 자재 공급에 대한) 공사를 수행하다 설계가 충분히 진행되고 핵심자재에 대한 견적이 입수되어 발주 가능한 시점 및 하도급사를 선정할 준비가 된 시점에서 1차 계약을 변경해 2차 계약을 맺는다. 2차 계약 시 1차 시 맺은 계약조건(직접공사비, 일반관리비 및 이윤, 최대한도 금액이 포함됨)을 기준으로 하되, 발주자가 Open Book 형식으로 공사비를 평가하고 재협상하여 Lump Sum 금액으로 전환해 합의한다. 이후 Lump Sum Tumkey 계약과 동일한 형식으로 공사를 수행한다.

Design-Build, one contractor is responsible for both the design and construction, has become more popular since the government framed the policy on how to activate the design-build projects in 1996. The reality is, however, there are many problems encounted on Contractor Selection Method for Public Design-Build Projects. The purpose of this paper is to improve the problems, no way to meet the goal(value) the owners expect from the design-build projects, for instance, not fully reflecting the characteristics of projects and owners intention, not systematical enough to judge if bidders could carry out the contract. This study will insist we introduce Best Value Procurement, which is being commonly used in some advanced countries recently, so that we would properly select the contractor suitable for Best Value concept which totally depends on the owners, types of work and specified conditions. Furthermore, by passing through the Two-Step Procedures following Pre-qualification in Best Value Procurement, we expect it lighten the bidders' burden for proposal and the owners' complicate bid administration.
